WG6401 D40P3 neck board transistor parts source

I am posting this pretty much for archive purposes. After years of just sitting there, I've really had the bug to get my Aztarac going. A friend of mine working on the WG19K6401 monitor found two bad transistors on the neck board, Q500 & Q501. The label was not readable on the actual transistor. The manual listed them as "Transistor D40P3 (NPN)".
   
  Our usual searches could find nothing on this. I called up Wells Gardner (they are actually pretty friendly people) and talked to one of the long time techs. Since they've moved locations, they've tossed a lot of the old documentation, but he did find something that identified them as a GE part. Not much, but turned out to be just enough additional info.
   
  After searching around, I found a couple sources for them, Direct Components Inc in Florida, 813-835-3883, $6 each, with a minimum order of $25, and JMS Electronics in North Hollywood CA, 818-764-3303. They had them for $3.50 each with a $50 minimum, but I happened to have a friend out there and JMS told me that if someone picked up in person, paid with cash (exact change) he'd sell them for $2.50 each with no minimum. My buddy picked them up the same day and mailed them to me. Popped them in and now I have another hurdle on the Aztarac crossed off. I found one other source, I can't even remember who right now, but their price was $10.50 each. Easy to see why I forgot them.
   
  FYI, an NTE171 is listed as a replacement (which is readily available), and I suppose it would probably work, but after looking at the specifications for each, we decided they were different enough to go with the original.
